To all whom it may concern:

Be it known that I, HENRY AUCHU, a citii'zen bf the United States, residing at Em porium, county of Cameron, and State of 5 Pennsylvania, have invented certain new and useful Improvements in Machines for 'Packing Dynamites and other High Explosives into Shells,-of which the following is a specification.

This invention relates to machines for packing dynamites and other high explo sives into shells which may be conveniently used for blasting and other purposes, this application being a division of my applica- 15 tion, Serial N 0. 573,993, filed July 26, 1910.

Dynamites and other high explosives are most frequently packed into paper shells by hand on account of the extreme danger of the operation.

The present invention has for its object the provision of a novel machine, susceptible of many modifications, which will be adapted to automatically, rapidly and safely carry out the operation of packing the shells and 2 whereby a number of shells may be simultaneously packed, but the packing operation of each wi l be independent of the others, so that each shell or ruled.

In carrying out the invention, I provide means for gently but regularly packing the shells with the explosive; means for feeding the explosive to the packing devices; means for regulating the pressure of the 35 packing action; means whereby the packing operation will cease automatically when a shell is filled and which will permit any of the packing devices to stop when their shells are filled without interfering with the continuation of the packing of the remaining shells which have not been filled, together with various other improved and novel in strumentalities, as will more fully appear hereinafter.

In the accompanying drawings :Figure 1 is a side elevation, a part or" the hopper being in section; and Fig. 2, a front elevation.

The frame-work of the machine is shown 0 at 1, and 2 is an inclined hopper carried thereby which is provided with an open front and a wall 3.

The numeral 4 designates a feeder which has spurs or paddles 5 operating in the 5 lower front part of the hopper and adapted into the shells.

; 25, preferably will be satisfactorily packed to'gently urge the dynamite or other high explosive toward the feeding devices and The inclination of the-hopper bottom may be changed as desired; according to the consistency or nature of the explosive to be operated upon, so 'thatthe gravital action thereof will carry such explosive downwardly and forwardly to the feeder. "lhe front part of the hopper bot-- tom adjacent to the wall 3 is provided with any desired number of funnel shaped openings in which the removable funnels 6 are placed, the paper shells to receive the dynamite or explosive being shown at 7 and held in a split or divided holder 8, which'is suit-- ably supported by the frame 1. A'num'ber of these holders 8 may be employed in which the operator will place the shells 7'so that as soon as one set is filled, the holder'and the quickly removed and filled shells may be another holder with empty'shclls inserted in place thereof, thus insuring great rapidity of operation without any loss-of the explosive. On separating the halves of-the holder 8, the shells may be removed.

There are employed reciprocating packers of wood or soft material, one for each shell, having packing feet 26 at their lower ends. These reciprocating packers are suitably guided in the frame-work 1 and have upper brass rods 25 which are provided with set collars 13 having set screws and adapted to be slid up or down thereonand secured at desired point. These collars, according to their disposition, will engage one of the bearings 9 and limit the downward movement of the packers 25 and by their adjustment, the packers may be arranged to initially go down just far enough in the shells, when operated, to insure even and regular packing of the explosive therein from the bottom up. The removable disk weights 18 may be as many as it is desired to use according to the packing pressure requisite to properly t-amp or pack the explosive in the shells. According to the number of these disk weights or the avoirdupois thereof, the effective packing pressure may be regulated and means are thus always provided to accommodate the machine to any particular explosive which is being packed. It the weights 18 are not supported by the gage collars 13, they may be otherwise suitably arranged on the packers.

' I claim as new and desire vary said packer, a set collar adjustable length- Pivoted at 27 to the frame 1 are levers 28, corresponding in number with the packers 25, and independently connected thereto by linlrsor connecting rods 29. The operating shaft 38 carries'any suitable cams 31, one for each. lever- 28; and the rotation of this shaft 30 causes the cams to impart an up ward movement to ithe .p ckers 25, the weights causing the packers to descend and to gently but suitably pack the explosive in the shells. The parts are so arranged and proportioned that when the shell is filled, the lever 28 is positioned so that the cam 31 of that articular packing apparatus cannot touch it and hence its cam will rot-ate without operating that particular packer. Each packing device is a unit and operates independently oi the remaining packers, so that the rate of *lling of the different shells may and some may be completely pacified before others have been filled.

Having thus described my invention, what to secure by Let-- ters ?atent, is:--

l. a shell packing or filling machine, the combination with a machine frame, of a shell holder, a packer-or tamper slidably mounted on said frame, operating means for wise or" the packer o'r tamper and positioned to engage the frame and limit the entry of the packer in a shell held by said shell holder, means for operating the packer or tamper, and cam. adapted to cotinerate with said means to operate the packer or tamper, said cam and means being relatively so arranged that they cease to cooperate with each other when the shell is filled.

2. In a shell packing or filling machine, the combination with a shell holder, of a reciprocating packer atively connected thereto, and'a cam adapted to operate the lever, the cam and lever being so related that when the shell is filled, the cam and lever will be out of cooperative relation,

or tamper, a lever oper- 3. In a shell packing or filling machine,

the combination with the machine frame, oi a shell holder, a slidably mounted packer or tamper, a collar carried thereby and adjustable lengthwise thereof adapted to engage the frame to limit the entry of the paclrer iii the shell, a plurality of independently removable weights mounted on the collar by which the pressure the packer applies to the explosive may he regulated, a lever for operating the packer, and a cam the lever, said cam and lever being so ar ranged that when the shell has been loaded they will be out of engagement whereby the movement of the packer will stop.
